UNITED STATES PATENT GEEICE.

SAMUEL A. MASSEY, OF FRANKFORT, KANSAS.

THREE-HORSE EVENER.

SPECIFICATION forming' part of Letters Patent No. 752,087, datedFebruary 16, 1904:.

Application filed October 12, 1903.

To all whom t may concern.:

Be it known that I, SAMUEL A. MAssnr, a citizen of the United States,residing at Frankfort, in the county of Marshall and State of Kansas,have invented certain new and useful Improvements in Three-HorseEveners, of which the following is a specification.

My invention relates to three-horse eveners, and has for its object toproduce a device of this character for use particularly on cultivatorsand wagons which will perform it function efficiently and reliably. l

A further object is to produce a three-horse evener of simple, strong,durable, and cheap construction.

With these objects in view the invention consists in certain novel andpeculiar features of construction and organization, as hereinafterdescribed and claimed, and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which- Figure 1represents a top plan view of a three-horse evener embodying myinvention. Fig. 2 represents a vertical section taken on the line II IIof Fig. 1.

In said drawings, l designates the tongue of a cultivator, wagon, orequivalent vehicle.

. 2 is a bolt extending vertically through the tongue at a suitablepoint, and mounted pivotally upon the bolt and at the upper side of thetongue and adapted for horizontal movement is the front evener bar orlever, said bolt extending through the bar or lever so that the arm 3 ofthe same shall beone-half the length of arm 4. 5 designates a secondbolt extending vertically through the tongue and disposed at a suitabledistance rearward of bolt 2, and mounted pivotally upon said bolt at theupper side of the tongue is the rear evener bar or lever. Said rear baror lever is by preference of greater length than the front one and isalso pierced by bolt 5 so that its arm 6 shall be half the length of itsarm 7 and, furthermore, so that its short and long arms shall project tothe same sides of the tongue as the short and long arms, respectively,of the front bar or lever, as shown clearly. At the side of the tonguefrom which said short arms project is a transversely-extending beam orlever 8, and pivotally unitserian. 176,672. zivomodeia ing the inner endof said beam or lever to the end of arm 3 is a link 9. A link 10pivotallyT unites the corresponding end of arm 6 with beam or lever 8 ata distance from the point of connection of the latter with link 9 aboutequal to the length of arm 6. by preference. l1 designates a linkproviding a swivel connection between the outer end of said beam orlever 8 and the doubletree l2, said doubletree being equipped, as usual,with swingletrees 13. 1li designates a transversely-extending beam orlever at the opposite side of the tongue, and the inner end of said beamor lever is pivotally united to the outer end of arm 4 by link 15. Alink 16 pivotally connects the outer end of arm 7 with beam 14 at adistance from the inner end of the latter equal to that portion ofbeamer lever 8 which lies between links 9 and 10, the relativeproportions of beams or levers 8 and 14 being such that their portionsoutward of the points of connection with links 10 and 16., respectively,are as two to one-that is to say, the outer portion of beam or lever 8is twice as long as the outer end of beam or lever 14. The outer end ofthe latter is united by link 17 to the swingletree 18.

From the foregoing it will be apparent that the double leverage giventhe two horses over the one, because the outer portion of beam or lever8 is twice as long as the outer portion of beam or lever 14, iscounterbalanced through the medium of the front and rear evener bars orlevers, the distribution being as follows: It takes one-half of saiddouble leverage to equalize the double leverage which the single horsehas through the medium of the front evener bar or lever and the otherhalf of said double leverage to equalize the single-horse doubleleverage obtained through the rearevener bar or lever. The result iswith the center hitch the tongue is carried as straight as though thehorse-power on each side was equal.

From the above description, taken in connection with the drawings, itwill be apparent that I have produced a three-horse evener whichembodies the features of advantage enumerated as desirable in thestatement of invention, and while I have illustrated and de- IOO scribedits preferred embodiments it is to be understood that Ireserve the rightto make such changes as fall within the principle of constructioninvolved.

Having thus described the invention, what I claim as new, and desire to.secure by Letters Patent, is

The combination with a vehicle having a tongue, of a three-horse evenerconsisting of a transverse evener-bar pivoted at unequaled distancesfrom its ends, to the tongue; a second transverse evener bar pivoted atunequaled distances Jfrom its ends, to the tongue, and having its longarrn at the same side of the tongue as the corresponding arm of thefirst-named evener-bar; a transverse beam equipped with a doubletree andaccessories at its outer end, and disposed at the same side of thetongue as the short arms of said evenerbars, and connected at its innerend to the front one thereof; a link pivotally uniting the short arm ofthe rear evener-bar to the said beam outward of the latters point ofconnection with the front evener-bar; a transverse beam equipped with aswingletree at its outer f end and connected at its inner end to thelong arm of the front evener-bar; and a link pivotally uniting the longarm of the rear evenerbar to the last-named beam at the same distancefrom its inner end as lies between the In testimony whereof I aHiX mysignature in the presence of two witnesses.
